UCTRONICS DC 12V Programmable Time Delay Relay Module — Metal Enclosure, 18 Modes & 0.1s–270h Timing

This timer module combines flexible timing functions with rugged protection and easy setup. Housed in a custom metal enclosure with cutouts for terminals, display, buttons and LEDs, the unit saves settings after power loss, includes reverse-polarity protection, and supports up to 10A switching at DC 28V or AC 125V. It’s built for applications from automotive lighting and motor control to Raspberry Pi and PLC signal integration.

How precise and flexible are the timing options?

The module supports delays from a tenth of a second up to 270 hours and offers 18 working modes, including single on-delay, off-delay, repeating loops, and trigger configurations with or without high-level voltage detection. That range covers short pulses and long intervals for automation tasks.

• Delay range: 0.1 seconds to 270 hours
• 18 selectable working modes for varied behaviors
• Supports infinite or finite looping cycles
• Configurable for high-level trigger or no-trigger operation

Will it survive typical workshop and vehicle environments?

The metal enclosure shields the timer electronics from mechanical knocks and provides secure mounting points while allowing clear access to the display and connectors. Built-in reverse-polarity protection reduces the risk of damage from incorrect wiring during installation.

• Custom metal housing with terminal, display, and button cutouts
• Reverse polarity protection to prevent module burnout
• LED indicators for status and mode feedback
• Compact size for dashboard, panel or box mounting

How does it integrate with my car, Raspberry Pi, or PLC?

The relay module accepts standard DC 12V supply and digital control signals, making it suitable as an add-on timer for automotive circuits, microcontroller projects, and industrial controllers. It’s compatible with NPN/PNP sensor outputs and PLC digital outputs that provide a positive voltage pulse.

• Operating voltage: DC 12V, quiescent current ~5.5mA
• Load capacity: up to 10A (DC 28V or AC 125V)
• Works with Raspberry Pi and Arduino via standard 12V-triggered inputs (use proper level-shifting when needed)
• Ideal for LED lighting, pumps, motors, and automation circuits

How easy is configuration and what happens on power loss?

Settings are saved automatically so you don’t need to reprogram the module after power interruptions. A simple button-and-display interface lets you choose modes and set delay durations without external software.

• Onboard display and push-buttons for mode and time setup
• Automatic saving of configuration to non-volatile memory
• Low standby quiescent current (approximately 5.5mA)
• Clear LED feedback during operation and programming

Who is this for: The UCTRONICS DC 12V Programmable Time Delay Relay Module is aimed at DIYers, automotive technicians, electronics hobbyists, and control engineers who need a reliable, configurable timer for switches, lights, motors and other loads. If you require a durable enclosure, a broad timing range, and compatibility with common sensor or PLC outputs, this module provides a straightforward, protected solution without the need for complex wiring or external controllers.
